Abstract (en)
[origin: WO2012038399A1] An optical system for producing simultaneous light emission in a first solid angle range (r1) around a first direction (R1) and in a second solid angle range (r2) around a second direction (R2) that is 180° opposite to the first direction, more particularly provided for an illuminator for producing light emission into the first solid angle range (r1) for direct illumination and for further light emission into the second solid angle range (r2) for indirect illumination, has a light source (2) for producing a light and an optical element (4) for deflecting a first part of the light into the first solid angle range (r1) and for deflecting a second part of the light into the second solid angle range (r2).
